trace_user_fault_put(9)

💅 trace_user_fault_put(9) 💅

okay bestie, welcome to the Kernel API Manual — this page is trace_user_fault_put(9) and it's lowkey a tiny little function but she's important, so let's get into it 🫶

---

✨ NAME ✨

trace_user_fault_put — dereference a per cpu trace buffer 🎀

✨ SYNOPSIS ✨

int trace_user_fault_put (struct trace_user_buf_info *tinfo );

✨ ARGUMENTS ✨

• tinfo — the tinfo that was passed to trace_user_fault_get. yeah, that exact one, no substitutions bestie 🙈

✨ DESCRIPTION ✨

so what she does is: decrement the ref count of tinfo. that's it. that's the whole job. iconique, no notes 💅

and then she gives you back the new refcount (negative on error 😭 — so if you get a negative number back, that's your vibe check failing, not a flex).

ngl the whole trace_user_fault_* squad is basically a get/put situation — you get it, you put it back, and the refcount stays happy. don't leave her hanging, fr fr 💀

okay that's the page!! this lil gem lives in ./kernel/trace, she's stamped October 2026, and that's the whole Kernel API Manual moment — mwah, slay, go decrement something responsibly 🦋💖✨
